The Partial Test Ban Treaty is signed in Moscow
The United States, the Soviet Union and the United Kingdom agreed to stop nuclear testing in the atmosphere, in outer space and under water, leaving underground testing permitted. The negotiation had failed repeatedly on the verification of underground tests, and the treaty succeeded precisely by excluding the case that could not be verified. Its immediate effect was environmental as much as strategic — atmospheric testing had been depositing fallout globally — and it established the pattern that arms control advances where verification is technically possible and stalls where it is not.
Historical — it happened, and the record is settled.

The Cold War: A New History
Named as the general narrative authority behind this pack's framing of the period, and cited in the Journey's own declared references. V55 verification basis: NOT consulted in this session. It is also a work with a definite interpretive position — broadly, that Soviet conduct drove the confrontation and that Western pressure and Soviet internal failure ended it — and this pack cites it as one reading rather than as a neutral summary.
